- A
Convert to Cloud SQL for PostgreSQL
PostgreSQL is open-source, eliminating Oracle license fees.
- B
Migrate to Firestore
Why wrong: Firestore is a NoSQL document database, not suitable for relational workloads.
- C
Use Database Migration Service (DMS) for homogenous migration
Why wrong: DMS only helps with migration, not reduction of licensing costs.
- D
Use Bare Metal Solution for Oracle
Bare Metal Solution allows running Oracle on dedicated hardware, reducing license costs compared to on-prem.
- E
Migrate to Cloud Spanner
Spanner is a fully managed relational database with no Oracle licensing.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Convert to Cloud SQL for PostgreSQL
Migrating to Cloud SQL for PostgreSQL eliminates Oracle licensing costs and modernizes the database while maintaining relational capabilities. Bare Metal Solution provides dedicated infrastructure for running Oracle workloads on Google Cloud, reducing hardware costs and enabling eventual modernization. Cloud Spanner offers a globally distributed, horizontally scalable relational database service, avoiding Oracle licensing and providing a modern architecture. Option B (Firestore) is a NoSQL document database, not suitable for large Oracle migrations. Option C (Database Migration Service for homogeneous migration) is a migration tool, not a long-term strategy, and would keep Oracle licensing if migrating to another Oracle platform.

Key takeaway
Cloud SQL for PostgreSQL
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
